In order to improve the cleaning effect and efficiency of the aluminum package used for carrying electronic aluminum liquid a new cleaning machine of aluminum package was put forward. Three standard cutters is used in new equipment to mill the inner cylindrical surface and end surface by moving in an epicyclic way. The cutting efficiency could be enhanced due to the appropriate capability carried by the cutters. The radial adjusting device of the cutter disk make the processing range flexible, thus increase the applicability of the equipment. Based on the analysis and research on the cutting devices of the new-structure aluminum package cleaning machine and the simulated to the machine processing it is demonstrated that the strength and stiffness of the cutting devices are qualified, and the design of the cleaning machine tool is practical.
